Adding a roof over a patio

Newbie here, my wife and I are looking to put a roof over our big patio. We would be connecting the new roof to our exsisting roof off of our house.

Question is, what is the wood called where you can put a shingles on it and the nails don't show through on the bottom, which makes the ceiling look nice? I saw this on the lakehouse episode on Indoors Out.

Thick.

All kidding aside, I'm not familiar with any one product that solves this problem. Typically a finished ceiling board would be installed first, fastened to the ceiling joists/rafters and then another layer of plywood/OSB would be installed over that to give enough thickness so the nails don't penetrate.

Yes, I just looked at the pics of open beam and that is kind of what we are wanting, but I won't need the big beams. How thick does the wood need to be so that the nails don't show? A contracter suggested he would do a rubber roof but I don't know anything about them, are they cheap or expensive?

Rubber (probably EPDM) would be fully adhered, so there wouldn't be any nails except to fasten the metal edging around the perimeter.

Depending on the rafter layout, it might be possible to hit the rafters when nailing/screwing the drip edge which would eliminate the need for a 2nd layer of sheathing.
